Applications

The SDR1005-681K is ideal for use as a rectifier in power supplies, automotive systems, industrial electronic components, energy storage, and more. It can also be used in high current circuits, such as in power supplies, in power converters, DC to AC converters, and in voltage regulators. As it offers excellent current and voltage characteristics, it is suitable for use in switched mode power supplies (SMPS).

Working Principle

The SDR1005-681K is a single-ended power inductor, meaning it consists of two sections – the coil and the core. The coil is composed of a copper wire that is wound around a ferrite core. When a voltage is applied to the coil, current will flow through it, creating a magnetic field around the coil core. This magnetic field will induce a voltage in the opposite direction to the applied voltage and this produces a counter EMF. The counter EMF opposes the applied voltage, causing a decrease in current flow, and this is known as inductive reactance.The SDR1005-681K also has a built-in feature known as ‘Snubber Damage Prevention’. This feature is designed to reduce voltage spikes that occur during switching operations. When a voltage spike occurs, the Snubber Damage Prevention feature will limit the voltage to a safe value and prevent damage to the circuitry.

Advantages

The SDR1005-681K is a reliable component for high current and voltage applications. It has an excellent temperature coefficient, low cost, and excellent reliability. It also has a wide operating temperature range and good thermal shock capability. Its size offers excellent space savings and high density of components, making it suitable for various applications.

Conclusion

The SDR1005-681K Inductor is a versatile and reliable fixed single-ended power inductor that is suitable for a wide range of high current and voltage applications. It has excellent current and voltage characteristics, and its unique features such as Snubber Damage Prevention, offer superior performance. It is a low-cost solution that offers excellent space savings and high density of components.
